I’m using FMOD 2.00.05 library on Huawei P20 and no sound can be played. I’ve tried sounds with samplerate 48000 / 41400 / 32000 and same thing, no sound. the error is 2019-11-15 00:35:32.510 3196-3223/?

But FMOD is implemented using this type of support. more details in this log: 2019-11-15 00:35:32.507 3196-3223/?

I cannot see any FMOD logging in there, do you have a log file with any/more FMOD information? ---

The issue was resolved after changing the initialization way FROM ```auto FmodSfx::FmodSfx(FMOD_SYSTEM* pSystem, FileStream* pFileStream, FMOD_SOUND_FORMAT format, bool bIsStream) { m_pSound = NULL; FMOD_RESULT result; #ifdef TARGET_ANDROID char pPath[1000] = {0}; sprintf(pPath, "file:///android_asset/%s", "sound1"); result = FMOD_System_CreateSound(pSystem, pPath, FMOD_LOOP_NORMAL | FMOD_CREATESTREAM, 0, &m_pSound); #else result = FMOD_System_CreateSound(pSystem, pFileStream->GetFilePath(), FMOD_CREATESTREAM | FMOD_LOOP_NORMAL, 0, &m_pSound); #endif } ``` TO ```auto FmodSfx::FmodSfx(FMOD::System* pSystem, FileStream* pFileStream, FMOD_SOUND_FORMAT format, bool bIsStream) { m_pSound = NULL; FMOD_RESULT result; #ifdef TARGET_ANDROID char pPath[1000] = {0}; sprintf(pPath, "file:///android_asset/%s", "sound1"); result = pSystem->createSound(pPath, FMOD_DEFAULT | FMOD_LOOP_NORMAL, 0, &m_pSound); #else result = pSystem->createSound(pFileStream->GetFilePath(), FMOD_DEFAULT | FMOD_LOOP_NORMAL, 0, &m_pSound); #endif } ``` thank you for your support
